PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.

Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

For the proof-of-concept, the cells were manufactured to be larger than necessary to avoid unnecessary costs and lengthy manufacturing processes at this early stage. Sodium-ion intercalation batteries—i.e., Thus, insertion/deinsertion of sodium ions in a host material is much more difficult than that of lithium ions.

ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

The projects were selected as part of ARPA-E’s Mining Innovations for Negative Emissions Resource Recovery (MINER) program. The projects selected projects as part of the MINER program are: University of Texas at Arlington. Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals. Earlier post.)The

UCSD researchers improve method to recycle and renew used cathodes from Li-ion batteries via eutectic molten salts

Green Car Congress

Due to the rapid growth of electric vehicle markets, the worldwide manufacturing capacity of lithium-ion batteries is expected to reach hundreds of gigawatt hours per year in the next five years. The team is tuning this process so that it can be used to recycle any type of cathode materials used in lithium-ion and sodium-ion batteries.
